How to Take It
Check the label before you take this
This product combines a stimulant with a sleep-supporting ingredient, so there's no single good time to take it. Follow the label and keep it well away from bedtime.
With food
Rhodiola rosea does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
On the label
2 capsules taken one to two times per day or as recommended by your health care professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
